I just bought a Mata Hari and the playfield is in very bad condition. I'm optimistic I can get all the dust and dirt off (glass cover is missing) but I won't be able to repaint the missing central section. I thought about applying a water decal for the central area with the dagger and clear coating it afterwards. The problem is that I can't seem to find a good scan/picture of the playfield to use as a template for the decal. The backglass also is in very poor condition, a lot of paint has already flacked off.
I would be very thankful if somebody could send me an image of the playfield and of the backglass. I'd try to create decals for the playfield and maybe a translite for the backglass.
